 Noct. Eur. 94, 1857. 



A free translation of Lederer's characterization of the genus is as 

 follows : 



Moderate in size, wing form of Cladocera, but more slender, vesti- 

 ture smoother. 



Collar and thorax rounded, vestiture close, hairy, with an admix- 

 ture of flattened scales, without tuftings. Front not produced, ves- 

 titure short. Palpi ascending, very slightly exceeding the vertex, 

 the vestiture somewhat divergent, terminal joint short, obtuse, hori- 

 zontal. Eyes naked, lashed. Tongue spiral ; antennre filiform, in 

 the males of § A lengthily, in those of § B very shortly ciliate. 

 Breast and femora with fine, thin, vestiture ; tibite closely scaled or 

 with rather sparse divergent vestiture, the anterior short, with a stout 

 claw at tip. Abdomen closely scaled, in the female obtusely pointed 

 with a very short, usually somewhat exserted ovipositor ; harpes of 

 male slender, somewhat curved, the upper end of tip rather acute, 

 the lower rounded. 



Primaries moderately widening outwardly, the apex and anal 

 angle somewhat rounded ; ash-gray, iron-gray, or reddish luteous, 

 with the ordinary Noctuid maculation, which is, however, rather 

 delicate and sometimes confused. Ordinary spots small. Fringes 

 entire, unicolorous, like the surface of wings, somewhat glistening 

 Secondaries light ashen gray, or yellowish gray, with somewhat dif- 

 fused darker margin, which on the underside is limited by a narrow 

 line and therefore seems better marked.
